Around 100 Dublin-based pilots who are members of the Irish Airline Pilots' Association (IALPA) voted on Tuesday to strike on December 20 as part of a dispute over workers' rights, including its refusal to recognise trade unions.
The airline on Tuesday had previously insisted that any discussion of pay and working conditions should be discussed through management-controlled "employee representative councils".
Impact trade union spokesman Bernard Harbor said the union wanted to meet before Wednesday to confirm the airline was committed to engaging with staff and to outline how the recognition of unions would work.
One day of industrial action had been planned for Wednesday December 20 and would have mostly involved captains.
Chief executive Michael O'Leary said the airline would reconsider its policy of refusing to recognise labour groups.
Mr O'Leary spoke to the airline's chief captains across its nearly 90 bases.
GettyRyanair strike The airline has agreed to recognised the unions for the first time
The Irish carrier said it would hold talks with unions in Ireland, the UK, Germany, Italy, Spain and Portugal to recognize them as long as they established a committee made up exclusively of Ryanair pilots, "as Ryanair will not engage with pilots who fly for competitor airlines in Ireland or elsewhere". "Given the seriousness of the situation I think it would be good if they could move their diaries around and find availability".
Mr O'Leary said the pilots should call off the threat.
No details have been provided by the airline of how many, or which, flights are likely to be affected.
It adds that British and Italian unions have already agreed to meetings with the airline, and have called off the threatened strike in Italy.
The low-priced airline's refusal to recognise unions was at the heart of the model that transformed the small Irish regional airline into Europe's largest carrier by passenger numbers.
At this point, it seems that all eyes are on Ryanair to prevent this strike. "They've gotten our offer of recognition in writing and we're happy to meet them next week, which itself is the first act in recognising IALPA", Ryanair said.
